FORENSIC CHEMISTRY - 2018/9

Module code: CHE2033

Module Overview

The purpose of this module is to give students a fundamental understanding of forensic chemistry. In this second year module, we focus on the chemistry relating to specific evidence types, namely gunshot residue, explosives, drugs and toxicology, paint and glass. Casework examples are used to give students a broad understanding of how data is interpreted. This module interacts with material that students are taught through analytical chemistry modules and demonstrates the application of relevant techniques to forensic casework.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

The assessment strategy is designed to assess whether students meet the learning outcomes of the module.

Laboratory scripts marked and returned during the semester; discussion sessions; practise exam questions

Module aims

To consider the historic development of forensic chemistry and its linkage to advances in analytical technique

To introduce the chemistry underlying the use of physical evidence

To give an understanding of the physical methods used in characterising such evidence

To introduce students to the underlying science, safety and forensic aspects of fire, explosions and firearms

To consider the information available from forensic computing and photography

To introduce the chemistry of drugs and poisons, and their detection

To outline the forensic toxicology of the above areas

To develop team working in approaching a forensic investigation

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Provide students with hands on experience of current forensic chemistry methods by practical sessions and workshops

Provide students with an understanding of physical evidence and its chemical analysis through lectures, casework examples, videos and discussions.

The learning and teaching methods include:

Workshops (3 x 1 hour sessions)

Laboratory sessions (2 x 1 day sessions)

Lectures (33 total)

Exam tutorial

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
